Wirelessly Transfer Data at 2 Gbps


Not today or tomorrow, but soon. And with 802.11ac and 802.11ad coming, the future for wireless looks very bright. Cables could quickly become a thing of the past.

John Chan … 2Gbps Wireless Chip

Scientists from Singapore’s Nanyang Technological University (NTU)’s Virtus IC Design Centre of Excellence have announced a new microchip called Virtus (named after the design center) that promises up to 2Gbps wireless data transfers in mobile devices. This will theoretically allow users to transfer 1GB worth of data in under 5s. Not only would this make copying music and videos to and from phones painless, it could also be used to make streaming content from mobile devices to TVs and projectors more convenient.

The Virtus meets the upcoming IEEE 802.11ad standard, which is complementary to current Wi-Fi technologies such as 802.11n and the latest 802.11ac . The latter two work in the 2.4GHz and 5GHz spectrums, and are widely used for Wi-Fi networks. 802.11ad, however, uses the 60GHz spectrum and has the potential for much higher transfer speeds. The downside is that it has limited range and wall penetration, and is thus more suitable for short distance device-to-device communications.
